Spring and roller suggestion

[outcrydrummer]

Ok so just looking for some suggestions here for a 150 fox carbide.
Has the following mods:
uni filter
race exhaust
race coil
irridium spark plug
new stator/magneto
cvk 30mm pumper carb, re jetted
polished allum. intake stack
kevlar drive belt
prodigy race clutch
prodigy race clutch-bellhousing
prodigy race variator

I'll be doing some flat driving. I'd like to focus on mid range to top end. I had a 4 deg adv cdi with no rev limit in it but it failed so its back to stock for now.
I have the 1000 1500 and 2000 main spring and clutch springs and 11 and 12g rollers. I also have whats in the kart now. I just bought it so not even sure whats in it right now, I just know its geared kind of low for what I want to do with.

Also is there a way to identify the weights of the rollers by the color??? I'm going to swap em out tomorrow so it would be awesome to identify the weight rollers before going through the trouble of replacing them.

Thanks a million

Use a postal scale to measure your weights - They will probably be 14g each.
